MACHINE FOR MAKING CORRUGATED PAPER-BOARD.

Specification of Letters Patent.

Patented J 1108, 1915.

Application filed November 19, 1912. Serial No. 732,288.

My invention relates to a machine for' making what is commonly known as double faced corrugated paper board by applying a sheet of paper to a' single faced corrugated paper board, and the object thereof 1s 1n general to provide a comparatively snnple and efficient machine for producing an extremely strong and uniform quality of board of this character.

One object of my invention is to provide simple and eliicient means for holding the lining sheet in contact with the adhesive onto the crowns of the corrugatcdshect solidly and steadily as the paper'passes through the machine without any possibility of kneading of the paper such asoccurs when feed rolls are employed, such lining sheet being preferably heated in such a manner and by such means that all danger of scorching or burning the paper is avoided.

-Another object of my invention is to provide efficient means whereby when the machine is stopped the corrugated sheet is automatically removed from contact with the adhesive applying r'oll therebypreventing the adhering of such sheet to the roll during the period of stoppage and the consequent tearing of the paper when the machine is again started. I

Another object of my invention is to so construct the movable platforms or endless carriers and the bearings thereof that such platforms cannot become soiled by the lubricant used.

Other novel and advantageous features of construction and operation will be apparent from the description hereinafter given.

In the drawings Figure 1 is a side elevation of my machine with the central portion thereof broken away; Fig. 2 a section on the line 2-2 of Fig. 1 but on a larger scale; Fig. 3 a perspective view of the cutter; Fig. 4 a longitudinal sectional elevation ofthe machine illustrating the front end thereof; Fig.

5 a similar view illustrating the rear end of.

the machine, these two. figures 4t and 5 when combined illustrating the entire machine;

F ig. 6. a longitudinal section of one of the.

rolls over which the lining or facing sheet passes and by which it is heated and Figs. 7 and 8 detail views of part of the cutting mechanism and of the lever 39 respectively.

Referring to the present embodiment of my invention as shown in the drawings, the machine is provided with front end frame 1 and rear end frame 2 and with any suitable number of standards 3 and cross bars 4 according to the length of-the machine.

It will be understood that this machine may be of any length desired, the longer the machine the more rapidly it can be run inasmuch as longer. time is given for the adhesive to dry. The end frames carry the Working parts of the machine and the standards and cross bars in particular support the endless carriers or platforms hereinafter described.

In the front end frame 1 is journaled the two shafts 5 and 6 to which are secured re-' spectively the sprocket wheels 7 and 8 of the upper and lower endless carriers or platforms.

On the rear end frame is journaled correspending shafts 9 and 10 and sprocket wheels 11 and 12 with the exception that these sprocket wheels are the driving wheels for-the endless carrier while the wheels 7 and 8 are merely idler sprocket wheels. These endless carriers or platforms are substantially similar in construction except that the lower platform is wider than the upper one. Referring to the uppermost carrier the same comprises the two side chains 13 and a series of lags 14: secured thereto. These lags extend transversely of the chains and of the machine and are ofsuch size that the horizontal reaches of the same constitute a substantially continuous platform or surface which on the lowermost reach is presented to the corrugated paper board passing through the machine. The other or lowermost endless carrier or platform is similarly composed of endless side chains 15 and the series of lags 16. As hereinbefore suggested the machine and consequently the endless carriers may be of any desired length. These carriers or platforms may be driven in any suitable manner and in the present instance the driving mechanism comprises the driving pulley 17 preferably driven by an electric motor (not shown), and secured to the shaft 9.- As shown in Fig. 5 this shaft carries a gear 81 which through "the medium of the train of the same sized gears 18, 18,

. drives a gear 19 secured to the shaft 10, with the result that both shafts 9 and 10 and con sequently the carriers are driven at'the same speed.

In connection with these endless carriersf carriercomposed of the chains 13 and lags 14 and runs loosely over the idler wheels 23 on shafts 24; suitably mounted in the end frames 1 and 2. The chains on their upper reach are supported by stationary tracks 25 which in turn are supported by the cross bars 4: of the machine. As clearly shown in Fig. 2 these chains are positioned along the longitudinal sides of the machine, and coiiperate with the tracks 1425011 the intermediate portion of the lags 1 1. As shown these chains are of the roller type, the side pieces of each link being wider than the diameter of the rollers. In a plane above the lower reaches ofthe chains'20 and the lags 14 pressure shoes 26 are provided the same lacing arranged longitudinally of the machine and in-a position to press the chains 20 downwardly upon the lags 14, These shoes may be made vertically adjustable in suitable manner so that any pressure can be put upon the paper. In the present instance I provide for this purpose the vertical adjusting screws 27' coiiper'ating with the supports 25 and the shoes 26.

The endless chains 21 are also of the roller type described and are supported on their upper reach by means of the longitudinal supports 28, these chains co'cipera'ting with.

the tracks 16 of the lowermost endless platform or carrier comprising the chains 15 and lags 16, the upper reach of such chains 21 supporting the lags 16 on their upper reach. These chains 21 extend at their ends over the idlers 29 on the shafts 30 mounted in the end frames 1 and. 2

The third set of chains 22 are also of the roller type the same passing over the idler rolls 31 on the shaft 32-mounted in the end frames 1 and 2. Such chains also have the supports 33'sirnilar to the supports 25 and 28 and in addition have a bottom support 34- for supporting the lower reach of the chains. However, these chains 22, unlike chains 20 and 21 coiiperate with the ends of the lags, and moreover. the lags 16 which they contact are formed thereat in the peculiar manner indicated in Fi 2 wherein it is seen that transverse recesses 16 are cut in the lags to accommodate the side pieces of the links leaving a track portion 16 for the rollers to contact with. Furthermore, these lags 1o are extended at their ends beyond the ends oi: the that the points of contact of chains z.re entered beyond the workingsurfe tiie lags 16 thereby avoiding ring; thereof by lubricant from 'the ch. .7.

At the has of the machine and upon. the p end frames 1 is reinovably mounted the 35 ada. :e to contain the adhesive such 1/ sihcate orpaste. Within the adhesive "there These levers are keyed to the shaft 37 so that manipulation of the lever 39 will cause a corresponding movement of-the ether lever. These levers are similar with the exception that the, lever 39 is provided with a dog 40 adapted to coiiperate with an adjustable plate 41 forming an adjustable stop for these levers. This plate is adjustable by means of the adjusting screw 42 coiiperating with a lugs?) forming a part of' the end frame.

Upon the shaft 37 is arranged an idler roller 44: over which the corrugated paper board A passes. These levers carry a hori zontal shaft 45 which is adjustable inside supporting levers by means of the adjust ing screws 16. In addition these levers carry an idler roller i -7 which revolves on the shaft 45 and over which the paperboard A'passes and by which it is presented to the roll 36 whereby the adhesive is applied to the crowns of the corrugations. In addition the levers 38 and 39 carry between them 1 a scraperiS adapted to cooperate with the roll 36 at a point below the point of application of the adhesive, the said roll 36 r0- tating in an anti-clockwise direction (Fig. 1). The roll 36 is driven in suitable manner as by means of the sprocket chain 19 and the sprocket wheels and 51, the former being secured to the shaft 5 and the latter to the shaft 36 of the roll 36. The construc-.

tion and arrangement is such that the surface speed of the roll 36 isthe same as the speed of the lags and consequently ofthe paper board A. presented to the roll. Movement of either one of the levers 38 and. 39 is designed to stop the machine and to automatically.withdraW the board A from the adhesive roll. -To this end the lever has attached to it a rod 39 which runs to switch (not shown) of an electric motor which is preferably employed asthe prime" mover. When the lever is thrown. rearwardly the switch is operated by the rod 39 to shut off thonurrent to the motor-and at the same time the board A isiwithflrawn from the roll. Also, by the same act the scraper is withdrawn from the roll the result that the adhesive on such roll above the scraper can run back into the pan. As clearly shown in Fig. 4 this pan is of such construction that it may be readily removed for cleansing purposes without disturbing any other part of the machine.-

The lining or facing strip B which is to be applied to the single faced corrugated board A is supplied from a roll 52 mounted in brackets .58 secured ,to the top of the end frame 1. The sheet B'passes over the two idler rollers 54 and 55 and thence in a 4 paper particularly when the machine is stopped, I prefer to heat them by water which is heated and kept heated bymeans ofsteam. As shown in the detail view in Fig. 6, the roller 54 is hollow and supplied with water. Entering the gudgeon 54 of one of the ends of the roller is a steam supply pipe 56 whose inner end is bent laterally so as to'always be immersed in the water. The other gudgeon of the roller is likewise hollow and provided with an overflow pipe 57 which takes care of any overflow occurring. particularly; when the water within the roller 54 is being heated. It will be understoodthat the other roller 55 is of similar construction.

The machine is continuous in its operation so long as the corrugated board A and the facing sheet B are supplied thereto and consequently the double faced corrugated board produced would be continuous but in practice it is desirable or necessary to cut this board product with accuracy, in predetermined lengths. In the present instance I have provided a simple and eflicient cutting mechanism for this purpose. This cutting mechanism is mounted. in the end. frame 2 and as shown in Figs. 1, Sand 5 the roll 58, preferably of hardened steel or chilled cast iron is mounted horizontallv in such end frame and adjusted vertically in suitable manner as by means of the adjusting screws 59 coiiperating with the journal boxes 60 for said roll, these journal boxes being movable in vertical slots 61 in the end frame 2. The lowermost point of this roll 58 is in the plane of the facing sheet B which was applied to the single faced corrugated board, that is in the plane of the top surface of the board product of the machine.

Journaled below the roll 58 is another roll 62 which carries in its periphery a series of radially disposed knives 63 extending the length. of such roll and projecting therefrom a distance sufii'cient to cutthrough the board product in coiiperation with the under surface of the roll 58. In the present instance, these knives 63- are two in-number, but one or more may be used; For the severing of the paper the roll 62 is automatically given a half turn when two knives are used or a full turn when one is used by the means illustrated in Figs. 1 and 7 As shown in Fig. 7 the shaft '64 ofroll 62 carries a sprocket wheel 65 over which extends a sprocket chain 66 which also passes over a. sprocket wheel 67 on the horizontal mov-,

able stud 68. The chain 66 is provided with detachable links, all of the links being ordinary plain links except those provided.

with lugs 69. These lugs are adapted to engage the peripheral shoulders or projee' .tions'ZO of a disk 71 secured to the shaft 64.

Each lug 69 is therefore adapted to engagethe disk 71 in clockwise direction (Fig. 5) thereby rotating the cutter roll62 a half turn or a full turn if two lugs are used near together. i The sprocket wheel. 65 is driven by the gear 72 secured thereto by bolts 73 and driven in, suitable manner as by means of the idler gear 74 driven by the gear secured to shaft 10.

In order to prevent any possibility of overthrow of the roll. 62, I key to. its shaft a brake drum 77, Fig. 5,.and provide a co operating brake band 78 to which'is fastened a weight 79. This brake band is connected at one end to said weight and atftheother end to a fixed point 80 on the end frame. Where only one knife is used in roll 62 additional lugs are used on chain 66 to give it one complete turn. I

Suitable driving mechanism may be employed for the cutter roll 58 and in the present instance such mechanism comprises a gear 81 secured to the drive shaft 9; pinion 82 journaled in the end frame 2 and the gear 83 secured to the shaft 84 of said cutter roll 58. It will be u'nderstood that the cutters are timed to move at a predetermined moment and at the same speed as. the paper product with the result that the board lengths are cut 'uniformly, rapidly and -without checking thefeed of the board or causing it to-buckle in front'of the cutters. Thev board lengths may be varied by the relative position of the lugs 69 in the chain 66. By preference sheet iron guards 85' are placed in advance of the cutting rolls to prevent wads of paper or the-operator from being caught between such rolls. It will be understood that the knives in the cutter head out against the hardened surface of roll 58 and sever the paper by pressure.
